The performance of motion-resolved whole-heart MR imaging strongly depends on the quality of cardiac- and respiratory-gating signals. While navigators or self-navigation can be used to account for respiratory motion, ECG is a mainstay for synchronizing data acquisition with the cardiac cycle. We tested whether physiological motion information, directly extracted from k-space-center, can replace respiratory navigators and ECG signals. The proposed solution was applied in 9 healthy volunteers and results were compared to those obtained with the ECG-signal. Correlation between R-wave time-stamps from the ECG and the cardiac self-gating signal was excellent, while image quality and coronary artery conspicuity remained unchanged.
